At present, people in which provinces of China burn kang.

There's a lot of upstairs that can really talk nonsense. It also burned kang in the three northeastern provinces and spread it to Shandong, Henan and other places. Most of the habits and diets in the Northeast are basically passed down from Shandong, except for a few locals.

Other provinces do not understand, there are kang in the rural areas of the Jiaodong Peninsula in Shandong, there are some in the city (you can't burn the fire), most of the other places in Shandong also have it, some places do not, there are in the northeast, and there are many rural areas such as Hebei and Tianjin. Also, does sleeping on the kang have anything to do with poverty? Nonsense, the top 100 counties in the northern region are almost all in Yantai, Weihai, Qingdao and other county-level cities.

In addition to the Yangtze River Delta and the Pearl River Delta, the south has the highest economic ratio here. Don't use the Yangtze River Delta to represent the entire south, and don't use the northeast to represent the north.

The burning of kang first originated in the three northeastern provinces (Heilongjiang Province, Jilin Province, Liaoning Province), and later with the passage of this custom to Shandong, Hebei, Beijing, Tianjin, Inner Mongolia and other places, the rapid development of science and technology, so that the custom of burning kang slowly faded out of people's sight, and now these poor places and the elderly still retain this custom.

Henan, Hebei, and Northeast China, some economically backward places in the north, are only part of the rural areas of the province, and not the entire province.

The whole north used to burn kang, and I still have kang here, and if you know the dividing line between the north and south of China, you will know where to burn kang, Qinling.

To the north is the north.

In the past, where it snowed, it was burned to keep out the cold. Like the place over there in Hunan. But now it's basically replaced with electric heating pads. Very few people go to collect firewood to burn the kang anymore.

The principle of the kang is to use the hot air generated by the combustion of fuels such as straw and branches to dissipate heat to the adobe when it passes through the flue of the fire, and the adobe is a poor conductor of heat, so the temperature of the kang will last after it is heated. The kang is composed of three parts: the stove, the kang body and the chimney. The stove with the kang can be cooked, and the kang body can be used for heating, and it can also be used to sit and lie down.

The chimney is a masonry kang exhaust flue for silver. The kang body has straight hole type, horizontal hole type, flower hole type, etc.

The ondol is a kind of masonry structure with a width of about 1.7 to 2.3 meters. Inside it is a brick wall with a flue in the wall between the kang. The kang has a stove and a smoke mouth, the stove is used to burn firewood, and the smoke and heat produced by burning wood pass through the wall between the kang to heat the stone slab above to generate heat, so that the kang produces heat.

Finally, the smoke is discharged from the ondol smoke mouth through the chimney.

Because the northern area of Dongkuzhou is relatively cold, it is said that it is necessary to heat up in the winter season, and the fire kang is because of a trace hall lifestyle formed over the years, and this kind of fire kang is more comfortable to sleep in winter.

Because the temperature in the Northeast is really too low, it is a waste of coal to burn heating, and it is too dry to turn on the air conditioner, so the fire kang can both cook and heat, why not?

In the three northeastern provinces of China, except for buildings, the vast majority of residents living in bungalows still live on hot kangs. There are many benefits to living on a hot ondol. In addition to being warm and comfortable, it also protects against rheumatic legs

The fire kang is now made of bricks. In the past, it was also made of adobe. Currently, bricks are used to build the kang, and the resistance is the "Huadong kang".

The kang and fireworks are evenly distributed in the kang cave, so the heat of the kang is uniform. However, no matter how evenly the kang heats up, there are subtle differences between the kang and the kang head. The kang is also slightly hotter than the kang head, therefore, there is a proverb in the Northeast that says that you don't know that the kang is a little hot - which means that you are neither good nor bad, do not know the importance, and do not understand the change of human feelings with temperature.

Northeast China and other regions are sparsely populated and the collective heating system is not perfect。Some villages don't have it, but the common people have their own way of heating, which is to burn the kang. There is a famous saying in the north:

Thirty acres of land with a cow, and the wife and children are hot on the kang. "From this sentence, we can see the popularity of kang in the north, especially in the northeast, and the love of the common people for sleeping on the kang.

The kang in the northeast is all wooden planks, and it's no problem to sleep on it with seven or eight people, so how warm is it? In fact,The thermal insulation effect of the hot kang is very good, the outdoor temperature is as low as minus 30 degrees, and the indoor temperature is as warm as spring, people sleep on hot kang until broad daylight, warmer than central heating. People in northeastern China have a long tradition of burning kang.

It can be said that the kang is a practical invention, and the weather in northeastern China is also relatively dry.

The kang does not feel very damp when sleeping, and lying on the kang can promote blood circulation, prevent and reduce the pain of rheumatism and arthritis

It may be because the fire pit is relatively warm, so most people still like to burn the fire kang, and the northeast is colder.

The doors and windows of rural rooms are not as sealed as those in the city, and the rural rooms are tall and large, minus 30 degrees at the coldest time, and the heating and floor heating cannot withstand it, and the rural kang is comfortable.

This is because the tradition of burning a kang in the countryside has been inherited.

Because the warmth of the kang soil is very good, it will not be as uneven as rice and cement, and people cannot use air conditioning to replace the ondol.

Because the environment in the Northeast is quite dry and cold, it is easy to keep warm by burning the ondol.

Because it is very warm to see this thing on fire, there are many people who are willing to burn the ondol.
